Synopsis

Keywords: Lung, LungWe determined the feasibility of diagnostic high resolution pulmonary imaging on a commercial 0.55T scanner and compared the image quality to a ramped down prototype 0.55T scanner. 0.55T scanners can improve accessibility of MRI, due to their lower cost, ease of installation, and wider bore geometry. Previously, we showed robust pulmonary imaging at 0.55T using a prototype scanner with high performance gradients. In this work, we leverage our robust self-gated, concomitant and motion corrected reconstruction pipeline to enable diagnostic pulmonary imaging on a commercial 0.55T scanner with lower gradient performance.
